An iron rod of length 25cm weighs 196.5g.What will be the weight of an iron rod of length 1.6m?
Answer:
1257.6 g
Step-by-step explanation:
1 m = 100 cm
1.6 m = 1.6 * 100 cm = 160 cm
Use a proportion.
196.5/25 = x/160
25x = 196.5 * 160
25x = 31,440
x = 1,257.6
Answer: 1257.6 g

Solve the inequality.
5(w - 3) < 5w + 20
Answer:
-15 < 20
Step-by-step explanation:
5(w - 3) < 5w + 20
Distribute;
5w - 15 < 5w + 20
Subtract 5w from both sides;
-15 < 20
Answer:
w<5
Step-by-step explanation:
(5*w-3*5)<5w+20
5w-15<5w+20
5w-5w<20-15
w<5

A softball academy charges students an initial registration fee plus a monthly fee. The graph shows the total amounts paid by two students over a 4 month period. The lines are parallel.
Answer:
I can't actually see the graph but i'll try to help
Step-by-step explanation:
if we use the formula y=mx+b
m=monthly fee
b=initial registration fee
x=amount of months charged
y=total sum paid
So you fill in the formula using the values on the graph

Look at where the line intersects with the other line perfectly and find the two closest times when that happens, then go up and over and count it.
So for the first one it is: up 1 over 1. That as a fraction is, 1/1 and that equals 1. So the slope is 1.
For the second one it is up 1 over 2. That as a fraction is 1/2. So the slope is 1/2.
Hope this helps :)

Explain the rules for multiplication and division to convert units. How do you know when to multiply and when to divide to convert units of measurements
Answer:
The basic rule is: If you need to convert from a larger unit to a smaller unit, multiply. If you need to convert from a smaller unit to a larger unit, divide. You will make the number smaller and, as you already know, division is all about making numbers smaller.
Answer:
addiemoss23/this person wrote this NOT me, it is right btw
Step-by-step explanation:
To convert units into smaller units, multiply. When the units are smaller , you need more of them to express the same measure. To convert smaller units to larger units, divide. When the units are larger , you need fewer of them to express the same measure.

Select all the pairs that could be reasonable approximations for the diameter and circumference of a circle. * 1 point A. 5 meters and 22 meters. B. 19 inches and 60 inches. C. 33 centimeters and 80 centimeters.
Answer:
B. 19 inches and 60 inches.
Step-by-step explanation:
Required
Select matching pairs
Represent diameter with D and Circumference with C
C is calculated as:
[tex]C = \pi D[/tex]
Where
[tex]\pi = 3.142[/tex]
A. D = 5m; C = 22m
Using: [tex]C = \pi D[/tex]
[tex]C = 3.142 * 5[/tex]
[tex]C = 15.71[/tex]
15.71 does not approximates to 22m.
Hence, the pair do not match
B. D = 19 in; C = 60 in
Using: [tex]C = \pi D[/tex]
[tex]C = 3.142 * 19[/tex]
[tex]C = 59.698[/tex]
59.698 approximates to 60.
Hence, the pair match
C. D = 33 cm; D = 80 cm.
Using: [tex]C = \pi D[/tex]
[tex]C =3.142 * 33[/tex]
[tex]C =103.686[/tex]
103.686 does not approximates to 22m.
Hence, the pair do not match
From the analysis above, only option B matches the diameter with the circumference

Which of the following is an arithmetic sequence with common difference 2
Answer:
D
Step-by-step explanation:
The arithmetic sequence with a common difference of 2 is 13,15,17,19. The correct option is D.
What is an arithmetic progression?The sequence in which every next number is the addition of the constant quantity in the series is termed as the arithmetic progression.
A number series is a number-based sequence. In the number series questions, we must identify the rules that lead to the formation of a number series.
The common difference is equal to 2. The arithmetic sequence will be written as,
13,15,17,19
Therefore, the arithmetic sequence with a common difference of 2 is 13,15,17,19. The correct option is D.

Colleen is selling tubs of popcorn to raise money for the school choir. Her goal is to raise $150. Colleen starts with 40 tubs of popcorn, and she has already sold
3/4 of them. If each tub of popcorn sells for $3.75, how much more money does Colleen need to raise to reach her goal?
Colleen needs to raise $37.5 to reach her goal.
What is the arithmetic operation?In mathematics, the arithmetic operation has four main operators such as addition, subtraction, multiplication, and division.
The symbol of + represents addition.
The symbol of - represents subtraction
The symbol of × represents multiplication
The symbol of ÷ represents division.
The goal of Collen is 40 tubs.
3/4 of 40 = 30 tubs.
Money for 30 tubs
⇒ 30 × 3.75 = $112.5
She needs
$150 - $112.5 = $37.5
Hence " Colleen needs to raise $37.5 to reach her goal".

What is the median of the follow 6 scores ? 64 , 72, 85 , 80 , 72 , 89
Answer:
76
Step-by-step explanation:
median is the number in the very center of the list of numbers in order:
64, 72, 72, 80, 85, 89
to find the one in the middle we take away the numbers from both ends:
72, 72, 80, 85
72, 80
since there are two numbers in the middle we’ll find the average
(72+80)/2
152/2
76
Answer:
76
Step-by-step explanation:
Median means middle
so we are looking for the middle number
place the numbers in order and look for the number thats in the middle
64, 72, 72, 80, 85, 89
72 and 80 are both the middle numbers.
Therefore, we add 72+80 and then divide by 2
72+80= 152
152/2= 76
Final answer: 76 is the median
Find the slope of the line with points (-1,-2) (2,7)
Answer:
3
Step-by-step explanation:
You may use this formula to find the slope of a line going through points [tex](x_1,y_1) \text{ and } (x_2,y_2)[/tex]:
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Notice the numerator is just a subtraction of the y's while the denominator is a subtraction of the x's. The order you choose your y's on top will matter to how you subtract the x's.
You could just line up the points and remember that the y difference goes on top and the x difference goes on bottom.
This is my favorite way.
(-1 , -2)
minus
(2 , 7)
---------
-3 -9
The slope is -9/-3 or 3.
You could do it the other way:
(2 , 7)
minus
(-1 , -2)
--------------
3 9
The slope is 9/3 or 3.

4y - 7 = 5x2 - x + 2 + 3y
Quadratic Equations
Options are No, One, Two.
I don't remember learning how to do it with more than a, b, and c variable. I'm so confused please help.
Answer:
y = 9 + -1x + 5x2
Step-by-step explanation:
Simplifying
4y + -7 = 5x2 + -1x + 2 + 3y
Reorder the terms:
-7 + 4y = 5x2 + -1x + 2 + 3y
Reorder the terms:
-7 + 4y = 2 + -1x + 5x2 + 3y
Solving
-7 + 4y = 2 + -1x + 5x2 + 3y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-3y' to each side of the equation.
-7 + 4y + -3y = 2 + -1x + 5x2 + 3y + -3y
Combine like terms: 4y + -3y = 1y
-7 + 1y = 2 + -1x + 5x2 + 3y + -3y
Combine like terms: 3y + -3y = 0
-7 + 1y = 2 + -1x + 5x2 + 0
-7 + 1y = 2 + -1x + 5x2
Add '7' to each side of the equation.
-7 + 7 + 1y = 2 + -1x + 7 + 5x2
Combine like terms: -7 + 7 = 0
0 + 1y = 2 + -1x + 7 + 5x2
1y = 2 + -1x + 7 + 5x2
Reorder the terms:
1y = 2 + 7 + -1x + 5x2
Combine like terms: 2 + 7 = 9
1y = 9 + -1x + 5x2
Divide each side by '1'.
y = 9 + -1x + 5x2
Simplifying
y = 9 + -1x + 5x2
